Abstract

The invention discloses a power-down fireproof protection pulse igniter comprising a single chip. The single chip is connected with a power supply circuit, a crystal oscillation circuit, a flame detection circuit, a buzzer alarming circuit, an ignition control circuit, an electromagnetic valve control circuit and a micro-switch; the power supply circuit is directly connected with a power source; the flame detection circuit is connected with a flame detecting needle; the single chip is provided with a port detecting unit for automatically detecting the state of the port of the micro-switch when the circuit is switched off and renewly switched on, and the single chip does not send an ignition signal to the ignition control circuit if the micro-switch is detected to be communicated, but sends a signal to the buzzer alarming circuit; and if the micro-switch is detected to be switched off, the single chip sends the ignition signal to the ignition control circuit when the micro-switch rotates. The invention has the beneficial effect of effectively ensuring the safe use of domestic fuel cookers under the condition of human negligence and incorrect firing solution and has the advantages of simple structure, security and effectiveness.

Description

technical field [0001] The invention relates to a gas pulse igniter used on indoor and outdoor gas stoves, in particular to a gas stove capable of identifying power failure and fire detection. Background technique [0002] At present, the pulse igniters used in the market mainly realize the following functions: safety self-inspection, ignition control, flameout protection, and fault detection. However, if the power supply is cut off or the battery falls off during use, and the gas switch is not turned off, the gas stove will automatically ignite the next time the power supply is connected normally. In addition, when a fire occurs in the pot during use, the gas continues to burn. These are all likely to cause fires when human negligence or improper disposal, and there are no safety protection measures for gas use. Contents of the invention [0003] The invention aims to solve the problem that the igniter of the existing gas cooker will automatically ignite after the power...
